Abstract
A manual activation system includes a bracket rotatable about a first axis between a first configuration and a second configuration and a pulley movable between an inactive position and an active position. The pulley is mounted to the bracket and is rotatable about a second axis. A tension member is wrapped about the pulley and has a tensile force acting on the pulley. An activation member is configured to cooperate with the bracket to selectively oppose the tensile force.
Claims9
A manual activation system for use in a fire suppression system, the manual activation system comprising:
- a bracket rotatable about a first axis between a first configuration and a second configuration;
- a pulley movable between an inactive position and an active position, the pulley being mounted concentrically about the bracket and being rotatable about a second axis;
- a tension member wrapped about the pulley, the tension member having a tensile force acting on the pulley;
- and
- an activation member configured to cooperate with the bracket to selectively oppose the tensile force.

A fire suppression system comprising:
- at least one source of fire suppression agent;
- and
- a manual activation system coupled to the at least one source of fire suppression agent, the manual activation system comprising:
- a bracket rotatable about a first axis between a first configuration and a second configuration;
- a pulley movable between an inactive position and an active position, the pulley being mounted concentrically about the bracket and being rotatable about a second axis;
- a tension member wrapped about the pulley, the tension member having a tensile force acting on the pulley;
- and
- an activation member configured to cooperate with the bracket to selectively oppose the tensile force;
- wherein fire suppression agent is releasable from the at least one source of fire suppression agent in response to a release of tension in the tension member.
